Download culture has its upsides, not least the demise of the surly men who dispensed music in specialist shops. Wisely, the venerable Rough Trade shop channels its staff's opinions into an annual double CD. US alt-folk (Bon Iver) and the indie-pop revival (Vivian Girls) are well represented on the house-trained CD1, where Brooklyn duo Telepathe outshine the competition. But the real dirt is on CD2, where noiseniks Shit & Shine and Flying Lotus fly the flag for electronic inventiveness and Dusk & Blackdown invest grime with existential angst.
